Does anyone know where I can get a bitmain S! Antiminer repaired? Seems one of the caps or something popped out approx 1/8 inch and now shows as dead. Or is it just a waste and for parts now? 1st one to go bad. Cry

If cap is the only reason for it's fault then it would be no problem and you can do it alone with semi-good quality soldering iron but caps in most cases blow like that (when it's just one) due to fault of component BEHIND them that draw their power.
Is it SMD (Surface mounted-tiny tiny  Cheesy) of regular (a little less in size than 1.5 V AAA battery?
Anyway transistors and MOSFETs can be changed too with low cost but you are better of getting someone qualified to do it (like a electronics repair shop).

We are talking about BIG Antminer not USB version right ?

If you try to fix it yourself make sure that you use new cap with more Voltage I.E. if an old one was 1500 mF 16 V replace with 1500 mf 25 V.

P.S. If it is cap on PSU part of the machine STAY AWAY FROM IT , high voltage current is not a thing to experiment with unless you know what you are doing (If it's 330mF 250 V for example it's PSU cap for sure).They can hold dangerous voltages inside them even if you unplugged the gear , it takes days for them to be fully empty and fixing those things can lead to even more catastrophic failure.

Guesses the above quote doesn't read but can only type,

DC has nothing to do with as per described in above quote that is AC stuff quoted, besides that its popped and has been off pwr for long enough for any other component to discharge, relax the 1st yr electronic tutorial, maybe if your talking about ballasts for discharge lamps and or tube TV's it applies, these units are fed DC and clearly the problem is not mentioned as psu but as the antminer.

For Ccynthia

Never mind the mind dump of the mF stuff,  

Also don't buy one of those heated solder suckers, just get a 10 dollar plastic one all up you can get away with a solder sucker Iron and solder for 40 bucks , to learn the soldering iron temp, practice melting some solder above some cardboard u want to be able to push wire on to iron at a slow pace and have it ball up on end of iron then wipe it off on a damp cloth, Just melt the new solder and it will melt the old.

1st year stuff, heat the pins not the board when replacing, pre-emptive for Gab

PM me and I can prob help you with a pic or 2, then your either on your way to an RA or a soldering Iron.

Never even saw one in real life , i assumed it had it's own PSU board.

BTW did cap just LEAP out of it's socket because of bad soldering or does is look
swollen or is there something leaking from it's top / bottom ? If it's true than it's
gone but don't assume that leaking 250 V cap can't hold a dangerous charge even
if it looks bad.

Even the 1/8 inch implies it is not 220/250v but 110v eg not AU/NZ.. Miners are running off DC even the big ass ones run off a AC to DC psu just like a computer or any other electronic equipment. there is no way on earth these ASICs could handle AC.

No point in mind dumping on people with pointless info in ones head, im sorry mate but really READ then RE read if it aint sync'ing.

Sorry  Grin Any electronics repair shop should be able to do the job.BTW you can only test caps once they are completely out of the circuit.

One cap change + new cap shouldn't be too expensive (10 to 30 $ maybe) + they will
have to check everything else related so you'd be good to go.

If you have a local friend who knows something about it he could do it for you for free.

You amaze me and I have been on safari and seen the stars through a telescope.

FYI u cannot test a visibly blown cap eg the 1/8 popping out bit,

If the person had a friend who knows something about it, Do you think they would be posting here.

To state the obvious only points out the dumbest person in the room and gives them great insight into your IQ.

Its moments like this you should seek shelter in a good book and please don't read an electronics book.

Grab a pillow mate, you have been weighed measured and found wanting thus branded "Junior Rocket Scientist"

I never read "visibly blown cap" part , only cap 1/8 inch out of the board ...

Direct current can zap you nicely and blown cap can be tested (it will say BAD) but some of them CAN hold a charge (LESS charge though).

There are caps that don't even look bad but are actually empty and not working ,  to be completely sure you need something that can measure capacity (ability to hold electrons) and to do that you first need to remove cap from the electric circuit otherwise
god will know what are you measuring.

like I said,,

1/8 as mentioned states that it is a visibly blown cap, and that was somebody that is asking questions, you should go back to problem solving minescape or something.

And just for shits and giggles what instrument would you test a bad cap on that comes back with a result of "BAD"

why would you bother testing a visibly blown cap, not even would you waste your time in the path of problem solving

your boring now

"popped out approx 1/8 inch and now shows as dead" doesn't spell blown , leaking and "shows as dead" can mean a lot of things.

Im guessing you do not and have not worked in a professional manner with electronics, Im guessing you work in retail with a passion for electronics that reads the magazines and does projects from the jaycar. I have no problem with that unless you inflict yourself onto a thread that was how ever many posts ago helping out a person with a problem which had I not pm that person would just look at this thread as a bunch of young ego minded tards with small hands.

Mind dumping is great in the right arena its how ppl learn from their peers, this person posted a question and your dumping like you have eaten nothing but laxatives for last 3 days, I have read all your other posts since you joined and I troll forums never post until it was needed, u jumped in with mind dump crap which had nothing to do with the problem but just a realease so maybe you thought you where - well what eva, I can guess your age and experience, go quiet for awhile,, this aint a gamming thread.

If all else fails, there is  RMA request: info@bitmaintech.com, assuming that it is still under warranty.
Does the whole Antminer S1 appear to be dead?  Are there any symptoms?
You may want to post a photo or more detailed description of the suspect part.

They all mean the same thing in this instance, like I said read then re read, then google research before you reply, just as a start to your problem solving skills which seems you want. Google may make you smart but it wont make you intelligent.

And im not attacking your intelligence, just please think out, then about your replying to posts that need fixing. Being the 1st to state the obvious, yada yada yada DERP

I used to fix computer motherboards and graphic cards for years but I didn't read the thread carefully , true , things I that learned I got from a trained old serviceman.

I'm actually 34 yrs old and got at least 300 repaired motherboards graphics and PSU's behind me that had bad caps , mosfets , mosfet drivers or generally fried chips on them but I will just stop answering to this.

Just cause im bored, 1 more time for the dummies.

1/8 and shows as dead , Does spell blown when the unit is dead, leaking which is not mentioned would show its an old cap or has been exposed to high heat.

Leaking caps are not blown in a workable device, this unit we speak of is dead, leaking caps give you a clue to what's going on, thus you would examine the device more intrinsically looking at darks points on other components and measuring the input of pwr if no dark components visible just as part of the problem solving process.
Electronics run off pwr that comes from AC then converts to DC. the 1st step in any problem solving with electronics is defining your array, your array is the total sum of things that can go wrong based on err then finding a halfway point eg if this tests ok and this doesn't my prob is on that side of things, the 1st place to array electronics is the pwr input - you confirm your psu and if external you look at what protects the device from a fail or fluctuating psu then so on and so forth, if you see blown caps you can of course take them out of line and test further on with the right test bench. In new devices you do assume the cap is faulty cause they are made in millions and tested 1 in a mill, examing the pcb also gives further clues but assumption is generally the best cost/time effective way.

damn said too much but when nubs start using mF and shit regarding 220/250v gear in regards to electronics I gotta say something,

Sorry Gab I belittled you or put you off electronics

cheers

If your fixing mobo and gfx your doing it wrong, they are and have been a replaceable component of computers for last 10yrs or more, unless you work for ATi or one of them brands your doing it wrong,

You can repair a some parts of a psu but NOT mobo's and gfx the boards are so multi layed not even do they fix, they swap some chips which as a service repair person you have no access to.  

If your gonna claim you solder onto or repair a mobo in the last 20yrs  

Just look at the side of a mobo or gfx, hue hue ,,

really dude,

Hahahaha don't be silly  Cheesy

Thing that closed our shop was general price drop of new stuff to the point it was more
profitable to buy new then repair old and outdated.

And now the same arms race in ASICs for Bitcoin mining disappointing  Huh  

I'm not buying anything else until they build something like this :

Sorry everyone for starting such a heated discussion over repairs.

I just finished contacting my second local college and found some interesting things about the bitmain s1 antiminer.

The motherboards are NOT normal boards and can not be soldered on. Heat will destroy them. Guess this is the future of motherboards now. They are only one sided boards with everything added in layers over layers using some form of adheasive/electrical process to make things stick and connect.

What happened on mine (and just realized it was a brand new one just got in 10 days ago) was the item pulled away from the motherboard completely. Just fell off. Piss poor workmanship all done by computers.

Of course I purchased several off ebay as new and can't return them so I'm out, my bad I guess. Anyway bitcoin is always a high risk venture and always will be for the time being.

Guess will be selling it for parts for best I can get. Just letting everyone know the motherboards are not like TV or computer boards etc. That is why they don't repair them. If they work good enough to pass test that's all they care. I have 7 computers and workstations and only 2 have similar motherboards where items (at least larger ones) can't be replaced without microscopes and some sort of fancy adhearing processs etc.
